OPERATING MEANS FOR SASH ADJUSTERS.

Apputionvnied December 16, 1921. serial No. 522,868.

To wZZ whom t may concern.'

Be it known that I, LOUIS Ro'rH, a citizen of Austria-Hungary, residing at the city of New York, county of Bronx, and State of New York, have invented a certain new and useful Operating Means for Sash Adjusters, of which the following is a specification.

This invention is an operating device for use in connection with means for imparting movement to a sliding sash.

As is well known, it is customary in some makes or styles of automobiles to employ a sash (one or more) in the body of the car for closing a window opening, and it is usual, also, to associate with said sash appropriate means of one form or another for raising and lowering the saine.

M improvement is directed, more particularly, to the member for effecting the manual operation of the sash adjuster, and to the means whereby said member is mounted for service within the car body.

The object is to provide an operating member which is not affected by the jar and vibration inherent in the movement of the vehicle, and the parts of which operating member are interchangeable with corresponding parts of similar operating mem` bers, which interchangeability of parts enables the operating member to be assembled and mounted with ease andv facility.

To these ends my invention embodies a base member provided with a bearing and with an o ening for the reception of a reliaft actuator having a handle and a bushing unitary one with the other, said bushing being provided with an annular groove and being mounted for free rotative movement within said bearing, a retainer occu ying the opening to the base member and gttin in the groove for precluding endwise disp acement of said bushing, and a collar tted to the base member in co-operative relation to the retainer so as to confine it in the opening and prevent displacement under the jar or vibration of the vehicle and to prevent said retainer from dropping out of osition by the operation of the device.

ther functions and advantages of the in- A vention will appear from the annexed description taken in connection with the drawin s, whereinigure 1 is a'view partly in elevation and partly in vertical section of my operating means for a sash adjuster.

' bushing is fitted snu Figure 2 is a transverse section in the plane of the dotted line 2 2 of Figure l.

Figure 3 is an elevation of the base member detached, and

Figure 4 is a detail perspective view of one form of retainer.

The base member A is a single piece provided with a boss a extending outwardly from the face plate a. Said member is adapted for fixed attachment to the car body interiorly thereof, and to this end, the face plate is provided with a desired number of apertures b through which screws b pass so. as to be embedded in the car body, see Figure 1. The boss of said base member is externally threaded for a part of its length, as at c, and said boss is provided also with an opening d extending through said male threaded part o, said opening being shown in the form of a slot, see Figures 2 and 8. The base member A is a fixed part of the operating device, and the boss a serves as a bearing within which is rotatably mounted a member of the shaft actuator.

Said shaft actuator comprises a bushing B and a crank handle C, the same being of unitary construction by casting said parts in one piece or by uniting the bushing and the crank handle in fixed permanent relation. The bushing is provided with an axial opening e of angular or square form in cross section, the external diameter of said bushing corresponding substantially to the internal diameter of the boss a, whereby the Gly within the boss so as to substantially pre'dlude all lost motion 'or idle play while at the saine time the bushing is free to rotate. within the boss. The length of the bushing is equal substantially to the thickness of the face plate and the length of the boss, whereby in assem# bling the shaft actuator relatively to the base member the face of the crank handle is in abutting relation to the end of the boss, whereas the inner end face of the bushing is flush, or substantially so, with the inner face of the face plate, see Figure 1.

It is important to preclude accidental separation of thewshaft actuator from` the` base member, thus overcoming relative displacement of the parts by the jar and vibration of the vehicle. In my invention, this function is attained by a retainer D cooperating with the bushing of the shaft actuator. As shown, the retainer is in the form of a key embracing a part of the bushing and fitting within an annular' groove f rovided in the external surface of said ushing, the groove being intermediate the ends of the bushing, said groove f being in registration with the slot d, and said rctainer key D occupying said slot d so as to fit snugly Within the annular groove. l

The retainer key D is a piece arcuate 1n form and provided with shoulders g, the external curvature of the key conforming to the external curvature of the boss, whereas the inner curve of the key is the same radius, substantially, as the radius of the groove f. This construction of the key enables it to be positioned within the slot d for thebuter ed e of the key to lie fiush with or slightly beiw the threaded face c of the boss, whereas the inner edge portion of said key enters the annular groove 1g so that the key embraces the bushing in a manner to preclude the bushing, and the shaft actuator as a unit, from displacement relatively to the fixed member A. The shoulder' g of the retainer key contact with the edges of the slot d at the ends thereof, see Figure 2, so that inward movement of the key is arrested to keep it from binding against the bushing of the shaft actuator.

E is a collar provided with a female thread h, the thickness of said collar exceeding the thickness of the retainer key, more 0r less. Said collar is screwed upon the male threaded part c of the base member for contact with the car upholstery F so as to impart a desirable finished appearance to the fitting, but said collar performs an additional function in confining the retainer within the boss, for the reason that the collar when screwed on the part c of said boss covers the slot d and the retainer occupying the slot. It will be apparent that the retainer occupies a fixed position within the boss restin by gravity upon the latter and within the ushing, so that the retainer is held in place by gravity and by contact with the boss and the bushing, but the use of the collar is 0f advantage for the reason that it covers the retainer, precludes access thereto by unauthorized persons, and' in effect locks the retainer against displacement.

All the parts of my operating device are standardized in that no special fitting or assemblage is required. In fact, the parts A, B, C, D and E are identical in construction with corresponding parts of other similar operating devices, and thus the pa'rts of one operating device are interchangeable with corresponding parts of other sinnlar devices, which interchangeability of parts is advantageous in assembling and applying the operating devices to an automobile body. Again, -there are no parts of my operating placement by theY jar and vibration of the automobile.

The device is assembled easily and applied with facility` The base member A is attached by screws b to the wall or other part of the car, and the bushing B is slipped into position within the boss so that the hub of crank C, or its equivalent, is in abutting relation to the boss. As is usual, the angular opening c of the bushing receives the squared end portion i of a spool shaft G so as to operatively connect the shaft actuator with the shaft to be operated so as to impart the required movement to the sash adjuster for raising or lowering the sash (not shown). The shaft actuator having been assembled with respect to the fixed member A, it only remains to place the retainer in position within the slot d, and to screw the collar E on the threaded part c of the boss,

lsaid collar operating to conceal the key and said collai` being screwed on the threaded boss until the collar binds tightly against the upholstery.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is 1. In an operating device of the class described, the combination of a fixed member provided with a male thread and a retainer aperture, a shaft actuator provided with a grooved bushing ada ted for free rotation within the fixed mem er, a retainer in contact with the fixed member and fitting said groove in the bushing, and a collar screwed on the fixed member and concealing the retainer.

2. In an operating device of the class described, a fixed member provided with a retainer-opening, a shaft-actuator mounted in said fixed member for rotation therein, a grooved bushing unitary with said shaftactuator, a retainer occupying the .retaineropening of said fixed member and withdrawable therefrom, said retainer being fitted in said groove of the bushing for precluding endwise movement of the bushing and the shaft-actuator, and means for conning the retainer within said opening of the lfixed member.

3. In a device of the class described, a shaft actuator embodying a grooved bushing and an operating element in unitary relation one to the other, a fixed member in which the bushing is mounted for free rotation, a retainer supported by the fixed member and occupying the groove of said bushing for precluding separation of said bushing from said fixed member, and a collar supported by the fixed member for precluding access to said retainer.
